Vaillant Gas Boilers Prices

Vaillant boilers are highly recommended throughout Europe for their efficiency and environmentally friendly designs. The Vaillant ecoTEC range of domestic boilers are made with the highest quality components and are backed up with market leading guarantee packages. With a broad range of combination, system and open vent boilers available, the Vaillant ecoTEC range will provide the perfect boiler for your home.

Vaillant Combi Boilers Price Range – Hot Water On Demand

Perfect for homes with limited space and/or smaller water requirements, Vaillant combination boilers heat water only when hot water is needed. Vaillant combi boilers are the most energy efficient boilers in the Vaillant range because they connect directly to the mains supply and don’t require a cold water tank or hot water cylinder. The only disadvantage to this type of boiler is that water pressure may not be as high as it would be with other types of boilers, especially if more than one tap is being used at the same time. Prices range from £850 to £1,920 with varying dimensions, flow rates and outputs.

Below, you can compare each combi boiler series currently available from Vaillant and find out which options are best suited to your home and needs:

Vaillant System Boilers Price Range – Eco-Friendly & Adaptable

System boilers are also known as sealed system boilers and provide hot water via a sealed system tank, which is usually housed in an airing cupboard. They do not require a cold water tank in the loft (unlike an open vent boiler) and they are advantageous in terms of satisfying high hot water demands. Vaillant system boilers can also be used in conjunction with other renewable energy heating systems such as solar thermal. Prices range from £780 to £2,800 with varying outputs to suit any home.

Designed for homes with greater hot water requirements, the Vaillant system boiler range includes the following options:

Vaillant Regular Boilers Price Range – Great For Larger Properties

Vaillant regular boilers (often referred to as open vent, heat only or conventional boilers) provide central heating and hot water via a boiler, a storage cylinder (which is usually housed in the airing cupboard), as well as a cold water tank in the loft. The tank in the loft draws water from the mains supply and then feeds the hot water cylinder. The water is then heated by the boiler and can be distributed throughout the property. It might take time to reheat once the water runs out due to it being cylinder driven but you can use taps, showers and baths in different rooms at the same time which is a necessity for larger families. Prices range from £796 to £1430 with varying outputs.

The Vaillant regular boiler range has been developed with small, medium and large homes in mind, and includes:

Key Questions for selecting your Boiler Installer

Ask your advisor key questions which will help make your decision on which boiler is right for you and your home. The key question is price and whether they will stick to the quote after the installation. Make sure there are no hidden costs. Ask them questions on their payment terms. How do these match against your own requirements? Do they install only A rated energy efficient boilers? Energy efficient boilers will save you money.

Crucially, make sure you review their safety record and expertise. All boiler installations today are done by Gas Safe Registered engineers. This ensures it’s done safely and legally. Another consideration is the flexibility on when your installer can fit your new boiler. Make sure their timescales are convenient to you. Lastly, ask them if they offer boiler insurance as part of their service. You’d be looking for the first year of cover to be free.

Comparing Boiler Quotes and Prices

For the best and cheapest boiler price, you will have to do some shopping around. Get a a quote from a national installer and a local boiler installer. Compare them on the cost of the boiler and the price of installation. Average installation costs are between £1,500 – £1,800. Comparing Vaillant Gas boilers prices could save you hundreds of pounds so it’s worth doing.

I have had an ecotec boiler for six years. Never again. It was recommended by the Energy Saving Trust, installed by a competent firm – and then the good things ended. In its short life it’s had major internal surgery and just like pressgirl’s comments above, various other parts have failed with the consequent cost of repairs and inconvenience. Its rubber hoses have perforated causing pressure loss and a fast switch off in case of rupture and tonight the timer has failed. Ok, that’s the timer’s first time but I’m starting to throw good money after bad. When the thing works it’s efficient and quiet and right for the size of the house but I shan’t recommend it to anyone and the plumber says it must have been built on Christmas day under protest!

I can echo the comments above from Pressgirl. I loved the Valiant boiler for 3 three years and then ….. the system has kept failing intermittently. Every winter is a nightmare as one does not know if the heating will work all winter or fail. Our gas engineer eventually asked us to call a more Valiant experienced engineer as he was at a loss and was unhappy at taking regular money from us.

The temperature control is totally not fit for purpose in this brand of boilers. It’s trying to be so clever that it gets it totally wrong. Factoring the outside temperature in the algorithm is one of those idea that sound great in theory but in practice is a total disaster. It makes the temperature control feature so unwieldy it’s simply unworkable. 4 years of trying to adjust the heating curve and making efforts to second-guess the algorithm and the temperature can still be out by as much as 6 Celsius (that could be either above or below the target temperature)! We have to adjust the control manually to avoid overheating or being cold. We have asked Vaillant if we cold just replace the temperature control with a bog-standard thermostat. But they don’t do that kind of product. I very much look forward to replacing this boiler with something simpler that actually works.

I can honestly say that Vaillant has without doubt the worst customer service (or lack of) that you will ever experience. They just basically ignore you until you go away. Had the misfortune of owning this vaillant ecotec unreliable piece of junk which was installed by one of their accredited installers for 4 years now … Stay well away and buy another make.

We have just had a Vaillant Ecotec boiler installed – not yet moved into the house but have the underfloor heating on. The boiler is installed in a very small hallway/lobby and we have noticed how much heat is being emitted from the boiler itself It is very significant so I am wondering about the insulation of the boiler itself. We would have thought the boiler these days would be very well insulated. Are there any views on this aspect.

Repairs had last been done about 10 years ago to a Vaillant Combi Boiler as per Br Gas recommendations, and so served 2 sinks, and 3 plus radiators (kitchen, bedroom, sitting room plus 1 small bathroom).

Vaillent pro24 combi fitted June 2012 major repair required 12 months one week after fitting warranty had run out by a week, and it continued for the next 3 years , to have repair after repair,it has now been installed for 4 years and another major repair,this boiler will be replaced next week and it will most definitely will not be a Vallient

Valiant boiler bought new when we moved into new house 5 years ago simply the worst product I have ever bought repairs required every winter and now looking to cut my losses and replace with a bosch valiant total rubbish
